theres no trend. i never mess with any contrast. only editing is a tweak of black tint and vignette. i've dimmed down my editing to pretty much two clicks...but apparently i wash them out and over edit.
my old dated pc makes them look like crap, and my macbook shows fuller vibrancy. i use my mac for everything so thats what i go by. (these don't show accuracy, but you can tell the difference)
